In;Crude oil entered the tiny annular space of lower shell, exterior ring cap, outer middle ring sleeve, interior middle ring sleeve and inner ring sleeve composition, and crude oil flow velocity increases
Greatly, overflowed from crude oil so as to accelerate gas, and the air accumulation for overflowing is existed by outer gas-liquid separation set, interior gas-liquid separation set
The top of lower shell, and steam vent by the second-order separation joint enters annular space.
The invention has the advantages that:Carried out using different rotating speeds using the reciprocating motion driving helical blade of sucker rod
Gas-liquid separation, the effect of gas-liquid separation is heightened by adding ring set increase crude oil flow velocity, and separate using gas-liquid separation set
The gas and crude oil of separation.
